Right now, (un)signed permutation representations use the generic RepByImages construction. And we recently switched to nonsparse matrices by default. Together, this makes things like `ComplexReflecti…

This is a follow-up on #504. It's been a while that I looked into this. I managed to write post-SCF natural orbitals to a molden file, but there is still a problem with documentation (http://www.psico…

Hi,
Does anyone know if there is a member function under DenseMatrix that can solve generalized eigenvalue problem, i.e. Av=\lambda Sv where A and S are of class DenseMatrix and they are symmetric po…

## I'm using arpack on visual studio 2015 + intel fortran 2017 to solve generalized eigenvalue of finite element method.
**I found that if nev is too small, the eigenvalue is completely error, like f…

Currently OpenPnP uses the fiducial data to calculate a board corner offset and rotation. When a board is not perfectly scaled from the manufacturer this can result in offset errors where the work is …

As we have observed several times e.g. #1, julias `eigs` is broken for a large class of generalized eigenvalue problems. As pointed out here https://github.com/JuliaLang/julia/issues/ 24668 this seems…

Hi Yihuan !
I'm interested in solving a generalized eigenvalue problem for Finite Element Method.
If the solver works well on small systems, it fails to extract the eigenvalues on a large sparse s…

I'm looking at trying to use umap on whole-genome data from the 1000 genomes project. I'm not doing lots of preprocessing, just filtering out variants with minor allele frequency less than 10% and loo…

### Description of the enhancement or error report
A new capability needs to be added to MOOSE to allow for the creation/filling of multiple Matrices/Vectors. This will be accomplished by declaring …
